I bought a HP Officejet Pro 6830 last year. The printer lasted about two months before it showed a printhead error. I got a replacement unit from HP that lasted 3 months before it had the same printhead error. I got another replacement and, guess what, it also had a printhead error but this time within four weeks.
HP even has a dedicated page for printhead errors on the HP 68XX series and the HP 6230, HP 68xx Printers – ‘Problem with printhead’ Error. Let me sum up the repair instructutions on that page: We send you a replacement unit.
If the problem expands to so many different printers and HP offers only replacement units the printhead error must be a major design flaw. Why do they even sell those garbage printers?
It really pains me to see that the company that for such a long time was the synonym for printer nowadays delivers a huge number of garbage unusable sub-par printers. Time to say goodbye to HP printers; at least for a while.
